Application led July 11, 1916. l Serial No. 108,555.

To all whom t may concern:

Be it known that` I, (EDWARD Soo'r'r, a citizen of the United States, residing at Pittsburgh, county of Allegheny, and State of Pennsylvania, have invented certain new and useful improvements in Power-Generators, of which the following is a specificatlon.

This invention relates'to power generators and has for its object to provide a generator in a manner as hereinafter. set forth, whereby the expandin gases from an explosion of a combustible mixture will be so directed as to be utilized for drivin a turbine.y

Further objects of t e invention are to provide a power generator which is simple in its construction and arrangement, strong,

durable, efficient in its use, readily set up either vertical or horizontal, and inexpensive to manufacture.

With the foregoing and other objects in view the invention consists of the novel construction, combination and arrangement of parts, as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views Figure 1 is a vertical sectional view of a generator in accordance with this invention showing the adaptation thereof in connection with a rotor or turbine.

Fig. 2 is a sectional plan.

Fig. 3 is a detail illustrating a partition.

Referring to the drawings 1n detail 1 .denotes a cylindrical casing, which is closed at its bottom as at 2, and mounted upon supports 3. The casing 1 has a head 4 for closing the upper end thereof and extending through said head 4 is a shaft 5 which forms a continuation of a turbine for rotor shaft 6. The turbine or rotor is indicated at 7 and `has theslraft 6 thereof extending through a cross head 8. The shaft 6 is operatively connected as at 9, with vthe machine which is desired to be driven.

The cylinder 1 is provided with a series of partitions 10, 11, 12 and 13. The partition 10, in connection with the head 4, pro- #vides a fan chamber 14., having an inlet 15 and ,a pair of opposed outlets 16, 17. Communicating with the outlets 16 is an L- shaped conductin pipe 18 and communicating with the outget 17 is an L/-shaped conducting pipe 19. The vertical portion of the pipe 18, has the inner side thereof, near its top, formed with a nozzle 2O which injects the expanding gases into the rotor 7. The vertical portion of the pipe 19, on its inner side, near its upper end, has a nozzle 21 which injects the expanding gases into the rotor 7. r1`he upper ends of the vertical portions of the pipes 18, 19 are connected as at 22, to the cross head 8 and the latter provides a closure for the upperends of thesaid p1pes.

The fan shaft 5 extends into the fan chamber 14 and carries a fan 23 having an inlet 25. The fan 23 constitutes what may be `termed an expeller and is employed for expelling the exploded gases, created in a manner as referred to, from the cylinder 1 and forces said exploded gases up land out through the pipes 18, 19, so that said gases will not remain in the explosive chamber to be referred to.

The partition 11, in connection With the partition 10, forms an explosive chamber 25 into which, near the top thereof, extends an igniter 26.

The partitions 11 and 12 form a gas and air mixing chamber 26?, the partitions 12 and 13 form a gas and air mixing chamber l27, and the bottom 2 in connection with the' compartment 13 provides anair partment 28. v

Each of the compartments 11, 12, and 13 is formed with a series of openings as indicated three in number, and designated 29, 3o, and 31.

'The ortion of the casing or cylinder 1 which orms the side of the compartment 28, is formed with a series of rows of openings 32. Preferably six-rows of openings 32 are employed, but this number can be increased or diminished and the said openings 32 are termed air inlets. Secured to the inner face of the casing 1, within the compartment 28, are Hap check-valves 33, which are utilized to close the openings 32 to shut oli' the force of the explosion from escaping.,through the air inlets. The length of .Leach lap check-valve is such as to exinlet compipes 36, 37 and 38 projecting therefrom.-

The pipe 36 has a nozzle ,or outlet 39 for discharging gas through `the opening 30,

the pipe 38 has a nozzle or outlet 40 for discharging gas through the opening'29, and the pipe 37 has a nozzle or outlet 41 for discharging The openings 29, and 31 referred to are those openings in the partition 13. The gas discharged from the pipes 36, 37, and 38, through the openings 29, 30 and .31 enters the chamber 27. Extending into the compartment 28 and connected to 'the couplingv 35, isa gas feed'pipe 42, which is secured as at 43, to the casing of the cylinder 1. The pipes 36,y 37, 37 and 42may be suspended from the partition 13 in any suitable manner.

When the fan or-expeller 23 is operated, the air is forced from the cylinder 1,l and permits of atmospheric pressure forcing the air into the compartment 28 through the openings 32 simultaneously with the supply of air through the openings 32, fuel gas will be supplied through the openings 29, 30 and 31 in the partition 13. As the gas and air pass through the openings 29, 30 and 31, the outer portion thereof is turned over by the walls of the openings, while the central portion freely moves over the openings andv in connection with the retarding of the gas and air by the partition, the gas and air mix, and such manner of mixing is also carried on as the gas and air pass from the compartment 27, through the openings in the partiton 12, thence through the compartment 26 and through the openings in the partition 11 and then enter the explosive chamber 25.

It will be assumed that the explosive mixture has entered the chamber 25 where it is ignited by the igniter 26 and the exploded gases are forced intothe pipes 18,

19 into the -rotor causing the operation of the latter. Back pressure from the chamber 25 passes down through chambers 26a, and 27 and into the compartment 28 and shifts the valves 33v so as to close the openings 32 and will also force the gas back into the feed pipe and interrupt the supply thereof. After the pressure has been relieved in the casing or cylinder 1, due to the exhaust of the expanded gases, gas and air will be supplied to the .compartments 26 and 27 so as to provide a combustible chamber and from the compartment 26 lwill enter the chamber 25 where it Will be exploded.
